Fastener



Aug. 20, 1957 N. ENGE FASTENER Filed Dec 2O 1956 v INVENTOR.

Moana Euere ATTOQMEYS United States Patent This invention relates generally to locks and the like for swinging closures disposed transversely of an access opening and is more particularly concerned with a novel separable fastener for swinging closure members.

Conventional hook and eye separable fastener on screen doors, for example, often causes excessive wear on the screen door or jamb for said screen door, often permit Y relative movement between the screen door and screen door jamb after the separable fastener is disposed in a latched position, and generally after constant use do not prove to be satisfactory.

A primary object of invention is to provide a novel separable fastener for swinging closure members utilized in conjunction with a jamb abuttingly engageable with one edge of the screen door, said fastener comprising a novel hook assembly including a mounting bracket incorporating means permitting elongated hook element to be vertically pivoted at one end thereon and further including means permitting arcuate horizontal movement of the hook against tension of a leaf spring portion, said bracket preventing excessive wear and marring of the finish of the members upon which the fastener is mounted, said hook incorporating a hook-end portion detachably engageable with a latch element and when so detachably engaged tends to draw the swinging closure member into a substantially sealed position against the jamb with which it cooperates.

Another object of invention is to provide in a separable fastener of the character set forth, a hook assembly incorporating a hook member pivotally mounted on a mounting bracket incorporating a spring plate, said mounting bracket including means for preventing the hook member from engaging and maning the finish of a cooperating closure member and jamb upon which the separable fastener is mounted.

A further object of invention in conformance with that set forth is to provide a novel separable fastener of the character involved which is readily and economically manufactured, easily installed, and highly satisfactory, practical for the purpose intended.

These together with other objects and advantages which will subsequently become apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a fragmentary perspective view of a portion of a swinging closure member abuttingly engaged with a portion of -a cooperating jamb, showing the novel separable fastener installed thereon, and showing by means of phantom lines the manner in which the parts cooperate to lock the swinging closure against its cooperating jamb;

Figure 2 is a vertical section view taken substantially on the plane of line 2 2 of Figure l;

Figure 3 is a horizontal section view taken substantially on the plane of line 3-3 of Figure 2; and

Figure 4 is a perspective view of a resilient plate element showing the manner in which the mounting bracket of the separable fastener may be constructed from a piece of stock material.

Referring to the drawing in detail, indicated generally at 10 is a fragmentary portion of the swinging closure including a side edge portion 12 abuttingly engageable with the side edge portion 14 of a screen door jamb indicated generally at 16.

indicated generally at 18 is a separable fastener comprising a latch element 20, which may comprise a conventional eye element including a threaded shank 22 terminating in a horizontally disposed eye portion 24. The latch element 26 extends laterally from member 16.

Indicated generally at 26 is a hook assembly comprising a L-shaped mounting bracket 28 including one leg 30 transversely apertured for having extended therethrough 1a suitable fastener such as a wood screw 32. Integral with the leg 30 and extending laterally out of the surface which is secured on the swinging closure 1i) are a pair of sharpened anchor lugs 34 for preventing rotation of the mounting bracket about the screw 32. The mounting bracket 2S includes a right angular resilient leg 36 which extends laterally from rthe swinging closure l0 toward spaced relationship from a plane extending vertically through the terminal end of the latch element 2t). Extending transversely through the leg 36 is a suitable pivot pin element 38 which has journaled thereon an eye portion 40 of an elongated hook 42 which terminates in a downwardly directed hookend portion 44, the terminal end portion 46 thereof being extendable into the eye portion 2e of latch element 20. The hook 42 is vertically pivotal :about the axis of the mounting pin 38, and the resilient leg 36 permits a horizontal movement of said hook toward and away from the latch element 2i). When the hook 42 is engaged with the latch element 20, the resilient leg 36 will be displaced in the manner clearly shown by means of phantom lines in Figure 3, and when the parts are disposed in this position tending to bind or urge the swinging closure into tight abutting relationship with its cooperating jamb,

For the purpose of preventing the terminal end 46 of the hook engaging the nish of the adjacent side of the swinging closure during its path of vertical pivotal movement, the resilient leg 36 has extending laterally from its upper and lower edges thereof reinforcing flanges 48 and 50 terminating in abutment ends S2 and 54, respectively, which abuttingly engage an intermediate portion of the hook 42 during its path of vertical pivotal movement for the purpose just mentioned. The resilient leg 36 will normally maintain the bracket land hook thereon in the solid line position shown in Figure 3, for example, preventing the hook 42 from engaging the jamb 16, thus protecting the finish thereof.

Considering Figure 4, there is shown a piece of suitable stock material indicated generally at 56 showing by means of dotted lines 58 the manner in which resilient leg 36 may be cut out or stamped out showing at 60 a fold line for defining the intersection between legs 3@ and 36, and showing at 62 the manner in which portion 34 may be stamped out, and further showing at 64 and 66 the holes through which the fastener 32 and the element 38, respectively, extend.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur tothose skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly 'all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

In a latch hook assembly, a resilient L-shaped mounting bracket consisting of a tirst leg securable to :a support, and a second leg on and extending at right angles to said first 3 leg, s aid second leg being exible in opposite directions outer abutment ends with which the latch hook is engagecrss-wise of said leg, and a latch hook having an eye able at different times. pivoted on a side of said second leg, said second leg being dongated fand having an Outer 6nd, Said latch hOOkey@ References Cited in the le of this patent being pivoted to said second leg at said outer end, and UNITED STATES PATENTS lateral reinforcing anges'on and extending along the edges 0f Said Second leg from said rst leg to points spaced in- 2,034,331 De Vilbiss Mar. 17, 1936 wardly from said outer end, said anges terminating in 2,093,180 Algeo Sept. 14, 1937
